Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490880, here are decompositions:

37 + 33490843 = 33490880
67 + 33490813 = 33490880
79 + 33490801 = 33490880
103 + 33490777 = 33490880
277 + 33490603 = 33490880
307 + 33490573 = 33490880
487 + 33490393 = 33490880
499 + 33490381 = 33490880

Showing the first eight; more decompositions exist.
